Abstract: Disclosed are a traffic transmission method and device, the method being performed by a terminal in a wireless communication system. Specifically, a non-access point (AP) STA of the present invention can receive, from an AP, a trigger frame triggering the transmission of a physical layer protocol data unit (PPDU). The trigger frame includes information indicating at least one traffic identifier (TID) that is allowed to be transmitted in a target wake time (TWT) period. The TWT period may indicate a period in which the transmission of traffic for the at least one TID having a specific transmission condition is allowed, and the transmission of traffic not having the specific transmission condition is restricted. Thereafter, the non-AP STA transmits a PPDU, including the traffic corresponding to the at least one TID, to the AP within the TWT period.

Abstract: A station in a wireless communication system is disclosed. The station includes: a transceiver; and a processor for controlling the transceiver. The processor receives a trigger frame for triggering uplink transmission from an access point (AP), and the trigger frame allocates, to the station, a part of a transmission opportunity (TXOP) acquired by the AP, as a shared TXOP, transmits a CTS frame as a response to the trigger frame, and switches a first enhanced distributed channel access (EDCA) parameter set used for channel access to a second EDCA parameter set based on transmission for the AP within the shared TXOP.

Abstract: Provided is a method for transmitting, by a terminal, a physical uplink shared channel (PUSCH) to a base station in a wireless communication system. The method comprises: a step for receiving, from a base station, an radio resource control (RRC) signal including configuration information on a semi-static uplink symbol, a flexible symbol, and a downlink symbol; a step for receiving a physical downlink control channel (PDCCH) for scheduling a PUSCH transmission including at least one PUSCH repetition; a step for determining whether at least one of the required number of symbols for transmitting the PUSCH repetition cannot transmit the PUSCH repetition; and a step for transmitting the PUSCH repetition to the base station on the basis of the determination on whether the PUSCH repetition cannot be transmitted. When the PUSCH repetition cannot be transmitted, at least one of the symbols is a symbol designated as a semi-static downlink symbol by the configuration information.

Abstract: A video signal processing method comprises the steps of: receiving information for prediction of a current block; determining whether or not a merge mode is applied to the current block on the basis of the information for prediction; when a merge mode is applied to the current block, obtaining a first syntax element indicating whether or not a combined prediction is applied to the current block, wherein the combined prediction indicates a prediction mode that combines inter-prediction and intra-prediction; generating an inter-prediction block and an intra-prediction block of the current block when the first syntax element indicates that the combined prediction is applied to the current block; and generating a combined prediction block of the current block by weighted-summing the inter-prediction block and the intra-prediction block.
